Soldered this usb hub to my ouya, works great. Attaching micro sd support and a custom case made from acrylic plastic to go with this, will post more updates very soon.

these are the soldering points.

I'm curious if it can run more than one thing at a time though without external power. Right now, if I hook an unpowered hub to my Ouya, plug in a fan and then a USB stick, it won't read the stick.

I noticed whenever you plug things into the Ouya they need to be plugged in before its turned on, I have plugged in a mouse, keyboard, and a micro sd usb adapter (with 8GB card) and they all work


could have also simply used a usb hub.

I am also building this into a case, so it will be an all in one instead of having extras hanging out, keeping the unit easily portable.

I would way rather use a powered hub, I am using a usb powered hard drive and it works fine.

Are you saying that there is an unused USB port on the board or are you simply connecting these wires to the existing external port?
An unused USB port would be super cool, but your post isn't clear.

I was wondering if you could help me i opened this usb hub up and i see there is 5 connections
and it does also have a plug for power if needed but would be fine by itself hooked up to the ouya
what wires would i solder to the MB?

from what I've found black is the ground red is V5 green is Data + white is Data -

like so

I think the blue wire on mine it for the optional ac power plug but I'm not sure
and I think my blue wire is there gray idk

The ground can be any colour, most manufacturers are different, Its the same in Car audio. That's why they urge you to read the manual when installing a new cd player etc.

so does anyone now if i could use this?
and if so how to hook it up?

UPDATE:
i tried this and hooked a usb fan which worked great but it would not read my usb power hdd it would blink in the usb hub hookups would light up in the orignal usb but still wouldnt read not til i cut the wires did it work

*squints* what usb hub did you use? (op)

~btw to jimlab7 I'm just guessing but black might be your ground, just solder that to the mb grounding areas? (like the shielding)
depends on the hdd sometimes though... might need a grounded hot or straight ground or just plain driver?

It seems that those solder points noted by the OP are tied to the external USB ports on the board and when you tied into these solder points for your fan you effectively put two USB devices on one USB port (endpoint). I bet if you connected your USB hard drive to the non-micro USB port via a micro-to-non-micro-USB adapter then your hard drive will work.

I see other soldering points under the non-micro USB connector, wondering if that has the same setup as the one under micro USB connector.

Like to get confirmation on the above, having multiple (more than three in this case) USB ports would be very cool, but it seems these are just soldering points to existing USB ports.

If his USB drive is unpowered, the "tap" for the fan might have drained the available 500mA available to the ports, leaving enough to spin and (sometimes) read the drive but not write it. Ran into this a few times myself on an unpowered hub.
